Notice that all of this is done so that a flex application in a browser can write to the local disk. Pretty clever, but this is where AIR makes life a bit easier. A Flex application using AIR can write to a local disk drive. Since the source code of JUnitTestRunner was available (thanks Peter), I was able to 1) learn something and 2) adjust the
sendResults function to write the result to disk.
private function sendResults() : void
{
for each (var report : Object in reports)
{
var xml : XML = createXMLReport(report);
var utf : String = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n" + xml.toString();
var file : File = new File();
if( m_basedir )
{
file = file.resolvePath( m_basedir + "/target/TEST-" + xml.@name + ".xml");
}
else
{
file = File.userDirectory.resolvePath("TEST-" + xml.@name + ".xml");
}
var fs : FileStream = new FileStream();
fs.open(file, FileMode.WRITE);
fs.writeUTFBytes(utf);
fs.close();
}
}
Next, was to compile the application in Ant as part of the CI process. Here is the target that calls mxmlc:
<target name="compile">
<java jar="${flex.home}/lib/mxmlc.jar" fork="true" failonerror="true" maxmemory="256m">
<jvmarg value="-Dapplication.home=${flex.home}"/>
<jvmarg value="-Dsun.io.useCanonCaches=false"/>
<arg line="-compiler.headless-server"/>
<arg line="-library-path+='libs/flexunit.swc'"/>
<arg line="-output='target/junitair.swf'"/>
<arg line="+configname=air"/>
<arg line="src/junitair.mxml"/>
</java>
<copy file="src/junitair-app.xml" todir="target"/>
</target>
The last task in the target copies the application configuration to the build directory. I have modified the configuration file with the following entry:
<content>junitair.swf</content>
Now to run the application - I admit that I cheated here a bit :-( where, rather than creating a "real" AIR application with it full signature and having to "allow" it to run everytime as it has been changed during the compilation, I use the adl executable as follows:
<target name="run">
<exec executable="adl" failonerror="true">
<arg value="target/junitair-app.xml"/>
<arg value="--"/>
<arg value="${basedir}"/>
</exec>
</target>
I've created a project that contains a
build.xml and the junitair.mxml application. Make sure to download the flex sdk. Create an environment variable FLEX_HOME that points to where you installed the sdk, and make sure that $FLEX_HOME/bin is in your path so that adl can be execute.
